manual targeting problems are giving me inaccurate firing solutions

[Captain Dave]

You sound like a candidate for the Dick O'Kane method of manual targeting.

Why did Rockin Robbins pull the range lever all the way to the right in the video? Is it because the target was so far away? If so, what do you do when the target is close?

Basically, with that method range is irrelevant (not entirely true, but close enough). Doesn't matter if the target is close or far away, same drill.

True indeed. The aiming tools of the fleetboat allow much "dynamics" in their use.

Dont forget the position keeper.


A hint:

Start with having "map contacts" on and compare your solution with the real situation.

Happy hunting.

This alone is a big help.

Also, if you are incorrect in identifying your target with the Rec. Manual, this throws things way off as well.

Stick with it and you'll catch on

When you pull the plastic triangle all the way down, you are manually setting the range at about 1425 yards. This will guarantee you a hit on any target from 700 to 2500 yards or so at a small gyro angle. If you leave the range at zero, you are nowhere near as accurate because something I can't explain is going on in the TDC to make the torpedoes' tracks go on a smaller gyro angle than you would expect. Even that anomaly probably won't make any difference under 1500 yards. But pulling the triangle down is making your solution just a little bit more accurate.

The Position Keeper Explained with apologies to PETA (on second thought, mail those idiots the dead duck.)
With the Dick O'Kane procedure, leave the PK off, as with all constant bearing shooting methods. To make it clear, if you were shooting innocent little duckies with a shotgun, there are two ways you can do it.

First you can sweep the gun to follow the bird and when you're satisfied with the lead angle you can pull the trigger at any time to kill the cute birdie. That is what the PK does.

Secondly, you can aim at a point ahead of the bird, holding the gun steady, and time the shot for when the duckie is at the precise position where the gun aimed at that point will hit the bird. This is how Dick O'Kane and John P Cromwell work with the PK off.

Both methods properly executed give your dog some exercise and extinguish the life of the innocent aquatic aviary creature.

Very good explanation indeed with the latter example being the way we aim with a germanU-boot (ie no PK).

Also I was not aware of the "triangle" -trick. Must test tonight

Cheers and thanks for the update.

It might have something to do with what's posted here:

http://www.subsim.com/radioroom/showthread.php?t=144057

Instead of having to point the bow or stern nest on the intended torpedo running course, the torpedo actually left the tube, ran a preset distance and enabled, then under its own gyro control, turned to its running course. It proceeded on that course until it either hit the target or ran out of fuel and sank.

Thus, the "actual" run consisted of two straight segments connected by an arc formed by the turning radius of the torpedo.

In tests, both the attack map display and the TDC dials began to go nuts as the distance to target approached zero. It's possible that, once inside 200 yards (where the "running course" no longer exists), the TDC can no longer calculate the proper solution. Instead, the computer is stuck with only one (of the two) straight segments ... making it impossible to correctly connect them with an arc.

What mods is he using in that video?

[Rockin Robbins]

What mods is who using in what video? Mine or Werner's?

I'd have to check the video now to recall in either case.:rotfl:

[Loud_Silence]

Im specially interested in that compass around the sub in the map
